Drumfin, Castlehill, Campbeltown

Dating to the mid-19th century, Drumfin and its accompanying former manse form a mirrored pair of double pile houses situated in Campbeltown. The buildings are designed with a U-plan, achieved by advancing the outer bays of each dwelling and angling the rear elevation to create a slight splay. They were originally conceived as a single composition.

The exterior walls are of stugged ashlar, with droved and painted details, contrasting with a rear elevation of coursed rubble and stugged dressings. Features include a base course, band course over ground floor lintels, a cill course at first floor level, and a cornice at the eaves. Window surrounds are architraved with projecting cills.

The principal (Main Street) elevation exhibits a near-symmetrical facade. The outer bays are advanced and topped with pediments. A bipartite rectangular window projects from the ground floor to the outer right, featuring a corniced parapet with crenellations. Ashlar entrance porches situated in the re-entrant angles are supported by square columns with capitals and bases, topped with a full entablature and corniced parapet, complete with pilasters at the corners.

The southwest elevation mirrors the design of the Main Street elevation, with a central, advanced and pedimented bay and matching outer left bay. The corner is set back and curved to meet the Main Street elevation, and the eaves cornice terminates around the corner to the left.

The northwest (rear) elevation is seven bays wide, arranged in a 3-4 grouping, with a central angled projection. The bays to the left are fenestrated irregularly and incorporate a single-storey over basement rendered wing with an attic, projecting at the outer left bay. This wing has a piended roof with a stone dormer breaking the eaves and a wallhead stack. To the right, the bays are narrow, with a ground floor door situated between them and a partially louvered brick and timber porch.

The original timber sash and case windows feature 12 panes, with 8 panes to the narrower rear windows. The porches have glazed infills with border glazing. The front door at Drumfin is timber-panelled, with a panelled inner door featuring a 12-pane upper section with bevelled glass, both with a rectangular fanlight. The former manse has a 2-leaf timber door with an etched glass inner door, also with a rectangular fanlight above.

The grey slate M-roof is piended at the rear wing and porch. A square section cast-iron downpipe runs down the center of the principal facade, with a decorative hopper and brackets, becoming circular elsewhere with a decorative urn hopper at the south corner. A variety of ashlar corniced stacks punctuate the roofline, including a 4-flue stack running centrally along the main ridges, a 3-flue stack at the north end, and single and 2-flue wallhead stacks at the rear elevation. The southwest elevation features a 2-flue stack at the apex of the pediment and at the wallhead of the curved bay to the right, with a curved shaft and a surviving original floreate can. Circular and octagonal cans are found elsewhere.

The interiors were not inspected in 1995.

Boundary walls of squared and stugged rubble enclose the entrance steps, topped with modern railings at the former manse and original railings with spear finials at Drumfin. Corniced gatepiers flank the southwest elevation, with the right pier integrated into the corner of the building, and metal gates providing access. A random rubble wall with a semicircular cope surrounds the sloping garden to the rear.
